Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597136, here are decompositions:

7 + 31597129 = 31597136
37 + 31597099 = 31597136
139 + 31596997 = 31597136
223 + 31596913 = 31597136
229 + 31596907 = 31597136
367 + 31596769 = 31597136
379 + 31596757 = 31597136
457 + 31596679 = 31597136

Showing the first eight; more decompositions exist.
